Marczyk Fine Foods is turning one of its most popular summer traditions — the Friday night hamburger cookout — into a fundraiser for the American Red Cross and Colorado wildfire victims.

The Red Cross Disaster Response will be the direct beneficiary of net burger sales on Friday 13 at both Marczyk locations: the Uptown shop at 17th Avenue and Clarkson, plus the newer outpost on East Colfax Avenue and Fairfax. The goal: Sell 400 burgers at each location.

Brian Glasgow, the store’s meat manager, has scored donated beef from Denver-based Niman Ranch, and fishmonger Jeff Prah is drumming up bands to play both venues. (The event runs 5 p.m.-7:30 p.m.)

For $6.99, you get to nosh on a chargrilled burger-on-brioche with tomatoes, lettuce, onions and condiments. Yes, that includes Marczyk’s signature bacon aioli. (Store owner Pete Marczyk views swine with the same fervor as Homer Simpson, which is to say, it’s a holy animal.)

For Glasgow, the fundraiser is personal.

“We have a family house in Glacier View, which was evacuated for six days,” he says. “Our house made it but we know so many people who lost their homes. It makes you happy and guilty all at once, and certainly makes you want to do something for these people.”
